On or about

On or about
Near; approximately; without significant variance from an agreed date.
The phrase on or about is used to avoid being bound to a more precise statement than is required by law. For example, when an individual seeks to purchase a home, the date when the transaction is closed and the legal title and possession are transferred from seller to buyer is ordinarily scheduled on or about a particular date. The phrase is used to indicate that the parties recognize the fact that, although the exact date might not be convenient for both of them, the transaction should be completed as close to that date as is practicable.
on or about
prep. a phrase referring to a date or place used in a complaint in a lawsuit or criminal charge if there is any uncertainty at all, in order to protect the person making the allegations of fact from being challenged as being inaccurate. Thus, a complaint will read "On or about July 11, 1994, Defendant drove his vehicle negligently and without due care on or about the corner of Sunset and Vine Streets..." (See: complaint, charge)
